Top vent assembly for kamado grill
A vent assembly that increases air flow and temperature control for outdoor cooking/smoking appliances, which effectively controls the space/gap for air exit, so as to improve air flow through the chimney and to increase temperature ranges and control within the smoker/chimney. The vent may have a gasket to make the grill waterproof and prevent mold when the grill is not in use. The vent can pivot or slide in one direction to ensure it does not open completely, so as to lose the air flow setting when the grill cover is opened or tilted.
1. A vent for an outdoor chimney comprising:
(a) a base having an open top and an open bottom; and
(b) a cap coupled to the base, the cap comprising
(i) a cover including two or more downwardly extending structures coupled to a bottom surface of the cover; and
(ii) a lower plate having a lower surface that rests atop the base, the lower plate including two or more upwardly extending structures coupled to a top surface of the lower plate;
wherein the downwardly extending structures and the upwardly extending structures define a space for gases to pass out of the cap; and
wherein the downwardly extending structures comprise at least one tab extending outwardly from each downwardly extending structure and the at least one tab may be used to slide the cover causing the downwardly extending structures to move with respect to the lower plate such that the size of the space is controlled by an interplay between the downwardly extending structures and the upwardly extending structures.
2. The device of claim 1 , wherein the vent is made of aluminum.
3. The device of claim 1 , wherein the base is cylindrical in shape.
4. The device of claim 1 , wherein the cap is cylindrical in shape.
5. The device of claim 1 , wherein the cap does not have openings in the downwardly extending structures or the upwardly extending structures.
6. The device of claim 1 , wherein diameter of the cap is smaller than the diameter of the base.
7. The device of claim 1 , wherein the upwardly extending structures and the downwardly extending structures of the cap are inset away from an outer edge of the cap and a cylindrical side wall of the base.
8. The device of claim 1 , wherein a gasket is disposed between the open bottom of the base and at least a portion of the outdoor chimney.
9. The device of claim 1 , wherein the cover of the cap is mounted to the lower portion of the cap and the cover is rotatable relative to the base.
10. The device of claim 1 , wherein a pivot point is formed by a screw which connects the cap to the base.
11. The device of claim 10 , wherein the pivot point is disposed proximate an outer edge of the lower plate such that that cap can be pivoted to expose the open top of the base.
12. The device of claim 1 , wherein the downwardly extending structures of the cap slide to align or adjust the size of the space between the upwardly extending structures.
13. A vent for an outdoor chimney comprising:
(a) a cylindrical base in fluid communication with the outdoor chimney; and
(b) a cylindrical cap in fluid communication with the base, the cylindrical cap comprising:
i) a cover comprising a first plurality of structures extending downwardly from a bottom surface of the cover; and
ii) a lower plate comprising a second plurality of structures extending upwardly from a top surface of the lower plate;
wherein the second plurality of structures is disposed outwardly from the first plurality of structures, such that rotation of the cover with respect to the lower plate causes the first plurality of structures to open or close a vent aperture disposed between a first structure of the second plurality of structures and a second structure of the second plurality of structures; and
wherein the cover is rotatable about a pivot point connecting the cover to the base and disposed proximate an outer portion of the base.
14. The device of claim 13 , wherein the vent is made of aluminum.
15. The device of claim 13 , wherein the diameter of the cap is smaller than the diameter of the base.
16. The device of claim 13 , wherein the upwardly extending structures and the downwardly extending structures of the cap are inset away from an outer edge of the cap and a cylindrical side wall of the base.
17. The device of claim 13 , wherein a gasket disposed between the open bottom of the base and at least a portion of the outdoor chimney.
